    UPDATE : I Finally got it running.. the issue was it was mssing the ignition control module..

    98 k3500 driving me insane. Wiring harness issues

    Well I compared the pinouts from the new harness to the hacked up one of the old harness and the pinout locations are different. I'm betting that's why I got no fuel pump so my question is should I try and get the ecu from the 2500 all this came from? (My head hurts this truck killing me)

    98 k3500 driving me insane. Wiring harness issues

    I will check it when the sun moves its 97 degrees here and the truck is directly under the sun no shade. But as for the other issue with no 2 sec prime or power to relay what are the chances the the harness pinouts to ecu being different amongst years and models? Ie 98 3500 vs 98...

    98 k3500 driving me insane. Wiring harness issues

    Yes have tried 2 different relays what is the possibility of the fuel lines being mixed up. They put them at the back of the motor on drivers side and have to be screwed in is it possible to mix them up or are they different sizes?

    98 k3500 driving me insane. Wiring harness issues

    Yes I have nothing until I jump the relay then I get pressure inside of the fuel rail which pushing the button allows the fuel to come out it comes out high pressure But at the same time it sounds like I have a broken line and gas is just pouring in to the intake whenever I jump bypass the relay
